It's a generic rebranded cheap chinese scope, search '3-9x40 EG scope' on youtube and you'll find loads of hits of the same scope, but with different branding.
As @EDcase says, there really is nothing to them in terms of controls - you have adjustment turrets for windage and elevation (remove the caps, you will see the directions to turn on the dial underneath), a rotating ring to adjust the magnification, and a dial to switch on and adjust the power/colour of the illuminated reticle which has the battery underneath the cap.
There are millions of these on Aliexpress (again search '3-9x40 EG scope') - you'll be able to work out the operation of the scope from the information pictures they post in the adverts as above.
